On Adding leading zeros on a bus in a schematic (.bdf) file

Hello guys !! I have a little question.. I'm using some vhdl objects in a schematic (.bdf) file. Now I want to add some leading zeroes to a bus eg: mybus[13..0] -> [0 0 mybus] In VHD...

Easiest to use named association.

Label the input to the VHDL as mybus. Do not connect it to anything.

connect a bus to GND. label the bus mybus[13..12]

connect the other part to the signal of interest, label is mybus[11..0]

Any reason you are using schematic and not VHDL?
